HL_PAN4 (Wyze Cam Pan v4) - IOTC_ER_UNLICENSE on firmware 4.70.1.3311

[namcbrid-hash]

Describe the bug

Wyze Cam Pan v4 (model HL_PAN4) fails P2P connection with IOTC_ER_UNLICENSE (-10) on both latest and dev tags of docker-wyze-bridge v2.10.3. Camera is discovered and added to streams, but never connects.

Bridge version

v2.10.3 (tested both mrlt8/wyze-bridge:latest and mrlt8/wyze-bridge:dev, sha256 89f2439f... for dev)

Camera model

• Model: HL_PAN4 (Wyze Cam Pan v4)
• Firmware: 4.70.1.3311 (latest production as of March 2026)
• Nickname: "Kaydence"

Relevant log output

[+] Adding Kaydence [HL_PAN4]
[kaydence] [-10] IOTC_ER_UNLICENSE

PTZ endpoints (e.g. /api/ptz_position) return timed out — the camera never reaches a connected state.

What I tried

• Switched from latest to dev tag — same result, same error
• Camera connects and streams fine in the official Wyze app
• Other cameras (non-Pan v4) work as expected

Notes / Questions

A few things worth noting based on research:

1. HL_PAN4 doesn't appear in the bridge's supported cameras table — only Pan v3 (HL_PAN3) is listed as the newest supported Pan model. Is HL_PAN4 intentionally unsupported, or is this a TUTK license gap?

2. TUTK SDK version — Is there a plan to update the TUTK SDK version to support newer Wyze firmware? The HL_CAM4 firmware update issue (BUG: Wyzecam v3 and v4 no longer work with bridge after auto-firmware update #1438) also surfaced TUTK license/compatibility problems.

3. Workaround? — Is there any known workaround (e.g. firmware downgrade, specific env vars, network_mode: host) that has worked for HL_PAN4?

4. v4fix fork — Saw nickdnj/docker-wyze-bridge-v4fix which uses WebRTC via AWS Kinesis instead of TUTK for HL_CAM4. Does that approach extend to HL_PAN4? Any plans to incorporate WebRTC support for Pan v4 into the main bridge?

Thanks for maintaining this project!
